Google launched the AMP Project (Accelerated Mobile Pages) back in 2015 in an attempt to speed up the mobile web. It's had its share of teething problems, but it's mostly been a success with its implementation in Search and the Google Feed. Last summer, it was reported that Google was working on "Stamp," which would combine AMP pages with an interactive storytelling element. That project has now come to fruition, with the announcement of AMP Stories.
